As shown in FIG. 1, the environment 100 may include a userdevice 110, a platform 120, and a network 130. Devices of theenvironment 100 may interconnect via wired connections, wirelessconnections, or a combination of wired and wireless connections.

The user device 110 includes one or more devices capable of receiving,generating, storing, processing, and/or providing information associatedwith platform For example, the user device 110 may include a computingdevice (e.g., a desktop computer, a laptop computer, a tablet computer,a handheld computer, a smart speaker, a server, etc.), a mobile phone(e.g., a smart phone, a radiotelephone, etc.), a wearable device (e.g.,a pair of smart glasses or a smart watch), or a similar device. In someimplementations, the user device 110 may receive information from and/ortransmit information to the platform 120.

The platform 120 includes one or more devices as described elsewhereherein. In some implementations, the platform 120 may include a cloudserver or a group of cloud servers. In some implementations, theplatform 120 may be designed to be modular such that software componentsmay be swapped in or out depending on a particular need. As such, theplatform 120 may be easily and/or quickly reconfigured for differentuses.

In some implementations, as shown, the platform 120 may be hosted in acloud computing environment 122. Notably, while implementationsdescribed herein describe the platform 120 as being hosted in the cloudcomputing environment 122, in some implementations, the platform 120 maynot be cloud-based (i.e., may be implemented outside of a cloudcomputing environment) or may be partially cloud-based.

The cloud computing environment 122 includes an environment that hoststhe platform 120. The cloud computing environment 122 may providecomputation, software, data access, storage, etc, services that do notrequire end-user the user device 110) knowledge of a physical locationand configuration of system(s) and/or device(s) that hosts the platform120. As shown, the cloud computing environment 122 may include a groupof computing resources 124 (referred to collectively as “computingresources 124” and individually as “computing resource 124”).

The computing resource 124 includes one or more personal computers,workstation computers, server devices, or other types of computationand/or communication devices. In some implementations, the computingresource 124 may host the platform 120. The cloud resources may includecompute instances executing in the computing resource 124, storagedevices provided in the computing resource 124, data transfer devicesprovided by the computing resource 124, etc. In some implementations,the computing resource 124 may communicate with other computingresources 124 via wired connections, wireless connections, or acombination of wired and wireless connections.

As further shown in FIG. 1, the computing resource 124 includes a groupof cloud resources, such as one or more applications (APPs) 124-1, oneor more virtual machines (VMs) 124-2, virtualized storage (VSs) 124-3,one or more hypervisors (HYPs) 124-4, or the like.

The application 124-1 includes one or more software applications thatmay he provided to or accessed by the user device 110 and/or theplatform 120. The application 124-1 may eliminate a need to install andexecute the software applications on the user device 110. For example,the application 124-1 may include software associated with the platform120 and/or any other software capable of being provided via the cloudcomputing environment 122. In some implementations, one application124-1 may send/receive information to/from one or more otherapplications 124-1, via the virtual machine 124-2.

The virtual machine 124-2 includes a software implementation of amachine (e.g, a computer) that executes programs like a physicalmachine. The virtual machine 124-2 may be either a system virtualmachine or a process virtual machine, depending upon use and degree ofcorrespondence to any real machine by the virtual machine 124-2. Asystem virtual machine may provide a complete system platform thatsupports execution of a complete operating system (OS). A processvirtual machine may execute a single program, and may support a singleprocess. In some implementations, the virtual machine 124-2 may executeon behalf of a user (e.g., the user device 110), and may manageinfrastructure of the cloud computing environment 122, such as datamanagement, synchronization, or long-duration data transfers.

The virtualized storage 124-3 includes one or more storage systemsand/or one or more devices that use virtualization techniques within thestorage systems or devices of the computing resource 124. In someimplementations, within the context of a storage system, types ofvirtualizations may include block virtualization and filevirtualization. Block virtualization may refer to abstraction (orseparation) of logical storage from physical storage so that the storagesystem may be accessed without regard to physical storage orheterogeneous structure. The separation may permit administrators of thestorage system flexibility in how the administrators manage storage forend users. File virtualization may eliminate dependencies between dataaccessed at a file level and a location where files are physicallystored. This may enable optimization of storage use, serverconsolidation, and/or performance of non-disruptive file migrations.

The hypervisor 124-4 may provide hardware virtualization techniques thatallow multiple operating systems (e.g, “guest operating systems”) toexecute concurrently on a host computer, such as the computing resource124. The hypervisor 124-4 may present a virtual operating platform tothe guest operating systems, and may manage the execution of the guestoperating systems, Multiple instances of a variety of operating systemsmay share virtualized hardware resources.

The network 130 includes one or more wired and/or wireless networks. Forexample, the network 130 may include a cellular network (e.g. a fifthgeneration (5G) network, a long-term evolution (LTE) network, a thirdgeneration (3G) network, a code division multiple access (CDMA) network,etc.), a public land mobile network (PLMN), a local area network (LAN),a wide area network (WAN), a metropolitan area network (MAN), atelephone network (e.g. the Public Switched Telephone Network (PSTN)), aprivate network, an ad hoc network, an intranet, the Internet, a fiberoptic-based network, or the like, and/or a combination of these or othertypes of networks.

FIG. 4 is a diagram of a 5G edge network architecture 400, according toembodiments. Edge Data Network (EDN) 401 is a local Data Network. EdgeApplication server (EAS) 402 and Edge Enabler Server (EES) 403 arecontained within the EDN 401. Edge Configuration Server (ECS) 404provides configurations related to EES 403, including details of EDN 401hosting EES 403. User Equipment (UE) 405 contains Application Client(AC) 406 and Edge Enabler Client (EEC) 407. EAS 402, EES 403 and ECS 404may interact with the 3GPP Core Network 408.

EES 403 provides supporting functions needed for EAS 402 and EEC 407.Functionalities of EES 403 may include: provisioning of configurationinformation to EEC 407, enabling exchange of application data trafficwith EAS; supporting the functionalities of API invoker and API exposingfunction, for example as specified in 3GPP TS 23.222; interacting with3GPP Core Network 408 for accessing the capabilities of networkfunctions either directly (e.g. via PCF) or indirectly (e.g. via ServiceCapability Exposure Function (SCEF)/NEF/SCEF+NEF); supporting thefunctionalities of application context transfer; supporting externalexposure of 3GPP network and service capabilities to EASs 402 over linkEDGE-3; supporting the functionalities of registration, update, andde-registration) for EEC 407 and EAS; and supporting the functionalitiesof triggering EAS 402 instantiation on demand.

EEC 407 provides supporting functions needed for AC. Functionalities ofEEC 407 may include: retrieval and provisioning of configurationinformation to enable the exchange of Application Data Traffic with EAS402; and discovery of EASs 402 available in the EDN 401.

ECS 404 provides supporting functions needed for the EEC 407 to connectwith an EES 403. Functionalities of ECS 404 are: provisioning of Edgeconfiguration information to the EEC 407, for example the informationfor the EEC 407 to connect to the EES 403 (e.g. service area informationapplicable to LADN); and the information for establishing a connectionwith EESs 403 (such as URI); supporting the functionalities ofregistration (i.e., registration, update, and de-registration) for theEES 403; supporting the functionalities of API invoker and API exposingfunction as specified in 3GPP TS 23.222; and interacting with 3GPP CoreNetwork 408 for accessing the capabilities of network functions eitherdirectly (e.g. PCF) or indirectly (e.g. via SCEF/NEF/SCEF+NEF).

AC 406 is the application resident in the UE 405 performing the clientfunction.

EAS 402 is the application server resident in the EDN 401, performingthe server functions. The AC 406 connects to EAS 402 in order to availthe services of the application with the benefits of Edge Computing. Itis possible that the server functions of an application are availableonly as an EAS 402. However, it is also possible that certain serverfunctions are available both at the edge and in the cloud, as an EAS 402and an Application Server resident in the cloud respectively. The serverfunctions offered by an EAS 402 and its cloud Application Servercounterpart may be the same or may differ; if they differ, theApplication Data Traffic exchanged with the AC may also be different.EAS 402 may consume the 3GPP Core Network 408 capabilities in differentways, such as: it may invoke 3GPP Core Network 408 function APIsdirectly, if it is an entity trusted by the 3GPP Core Network 408; itmay invoke 3GPP Core Network 408 capabilities through EES 403; and itmay invoke the 3GPP Core Network 408 capability through the capabilityexposure functions e.g., SCEF or NEF.

Architecture 400 may include a number of different interfaces forenabling edge applications, which may be referred to as referencepoints. For example, link EDGE-1 may be a reference point which enablesinteractions between the EES 403 and the EEC 407. It supports:registration and de-registration of EEC 407 to EES 403; retrieval andprovisioning of EAS 402 configuration information; and discovery of EASs402 available in the EDN 401.

Link EDGE-2 may be a reference point which enables interactions betweenEES 403 and the 3GPP Core Network 408.

In FIG. 5, the 5GMS Application Provider (AS) requests to 5GMS AF theprovisioning of the session using the M1 interface. Then, through thesame interface, AP requests provisioning of different session featuresincluding server certificate, content preparation, content hostingconfiguration, reporting, consumption reporting, policy, and others.

As discussed above, the current 5G Edge architecture defined in 3GPPTS23.558 only defines the discovery of the edge application byApplication clients. The 3GPP TS26.501 only defines the media streamingarchitecture. The 3GPP SWG4 recently developed an architecture forrunning 5G media applications on 5G edge servers by combining the twoarchitectures.

Accordingly, embodiments may provide a method of using the abovearchitecture for running live streaming services for user-generatedcontent.

In embodiments, an example use case may correspond to user-generatedlive streaming. The use-case can be summarized as the following. Asocial influencer starts a live captured media session and publishes thecontent through 5G Media Uplink Streaming. The content is thendistributed live to several or many viewers through 5G Media DownlinkStreaming.

Embodiments may provide several usage scenarios with variousconfiguration options which may change during the live session. Forexample:

-   1) The social influencer may:    -   a) be static, occasionally moving, or highly mobile, for example        in a vehicle, on skis, or on a bicycle,    -   b) produce different quality of content, depending on lighting        conditions, speed, as well as based on the quality of the camera        and the available uplink bandwidth,    -   c) produce highly valuable content that requires extra content        protection,    -   d) want to capitalize on the stream by allowing ad-insertion in        the content (targeted pre-roll and/or mid-roll).-   2) The viewers may be quite diverse and changing because:    -   a) they may be dynamically joining or leaving the live stream,    -   b) their number might be, just a few or they may quite many, in        the range of tens of thousands or more, for example for a        popular influencer,    -   c) they may be geographically spread with different densities in        various areas, and their densities may change during the        session,    -   d) they may consume the service on different devices, for        example on 4K TV sets, mobile phones, in-car receivers, or        tablets, with different operating systems, DRM capabilities as        well as different codec hardware capabilities,    -   e) some of them may be mobile, i.e on a car or public transport,    -   f) they may react (sniffles, comments, likes, audio dubs,        images, avatars, and animations) to the content or previous        reactions by the viewers who watched the content earlier.-   3) The service requirements may he quite different. The content may    need to be:    -   a) available for live and/or on-demand consumption,    -   b) only available for consumption after the end of the live        uplink session, i.e. it is uploaded entirely before being made        available to followers,    -   c) available with a required target latency with ranges in        between capture and display of as low as 1 second up to several        tens of seconds,    -   d) dubbed into the same or different language,    -   e) provided with automatic extraction and addition of        captions/subtitles from the audio,    -   f) post-processed to improve the audio and/or visual quality,    -   g) processed by adding overlays and content tags and other        augmented material,    -   h) indexed, including the addition of thumbnail navigation in        real time,    -   i) provided to regional proxies with specific metadata such as        black-out information, ad insertion opportunities, language        settings or other service metadata,    -   j) profanity checked and appropriately altered before being        distributed,    -   k) available for viewing for some time (from a few minutes to        forever) after the end of the live session.

According to embodiments, in a simple reference scenario of 5G MediaUplink and Downlink Streaming, one or more of the following aspects maybe supported:

-   1) An application manages the service. The server application may be    run by external application providers, by MNO, or by a collaboration    of the application provider and MNO.-   2) Uplink streaming is provided through 5G media uplink streaming to    the application.-   3) The application may perform one or more of the following    processes:    -   a) It decodes the received content    -   b) It applied the various processes the content such as:        -   i) Upscaling        -   ii) Light correction        -   iii) Stabilization        -   iv) Dubbing        -   v) Captioning        -   vi) Overlaying and tagging        -   vii) Indexing        -   viii) Navigation improvements.    -   c) It encodes the uploaded content to 5GMS downlink streaming        formats.    -   d) it packages the content and adds appropriate ad metadata.    -   e) It applies content protection and DRM.-   4) As soon as the content becomes available, the server application    uses downlink streaming for distribution.    -   a) It provisions a 5GMS downlink streaming service.    -   b) It ingests the content into a 5GMS streaming service.    -   c) it gets feedback from consumption reporting on what content        is consumed and may change the encoded streaming formats.

In embodiments, one or more of the following aspects may be importantfor the service:

-   1) Can the service be provided throughout the session without any    interruption considering the dynamic aspect of the service, for    example when a highly mobile edge media streaming client makes a    transition between two edge processing environments?-   2) Can the desired end-to-end latency be met with the reference    scenario and if not, what are possible ways to realize this?-   3) Is the content generation flexible and fast enough to address    different user populations, yet highly utilized, i.e. the variations    of the content is consumed by one or more viewers and is shared as    much as possible by many viewers?-   4) Is there a benefit to push certain processing closer to the    influencer, certain viewers, or in-between (in terms of bandwidth,    latency, and processing requirements)?

Service Class

Accordingly, embodiments may make use of service classes that may definethe set of services offered to a user. For example, user-generated livestreaming use case covers scenarios where various processing may occurdepending on a requested class of service. In many sessions, the servicemay occur in the cloud or at an edge close to the capturing device. Inthis use ease, an Application Provider, for example 5GMS ApplicationProvider 501, may define various classes of service.

Each class of service, which may be referred to as a Service Class, mayprovide a content preparation process that supports one or more specificfeatures from the list below:

4) Splicing and ad insertion

-   -   a) Splicing content and manifest signaling    -   b) Ad insertion queues and information    -   c) Language setting and other service metadata    -   5) Applying content protection and DRM

Service Class Requirements

For each SC, a set of Service Class Requirements (SCR) may be definedfor a 5GMS AS running the service, which may include one or more of thefollowing aspects:

1) EAS type
